Secretary General Jens Stoltenberg urged Russia to end its support for the Assad government:

“Russia’s military escalation in Syria raises serious concerns. I call on Russia to play a constructive role in the fight against ISIL but Russian actions and support for the Assad regime are not helpful.”

NATO member Turkey has complained that Russian warplanes violated its airspace twice recently as part of military involvement in the Syrian conflict.

“The recent violations of Turkish airspace are unacceptable. NATO is ready to defend and protect all allies against any threat and that, of course, also goes for or is valid for Turkey,” said Mr Stoltenberg.
